Magnification changes by specialty
A 2004 peer-reviewed survey of 148 specialists and senior trainees in the west of Scotland (Jarrett, Microsurgery 2004) found clear specialty patterns in intraoperative magnification use. Plastic, maxillofacial, ophthalmic, and otolaryngology surgeons reported frequent use of magnification, cardiothoracic and pediatric surgeons leaned heavily on loupes, and neurosurgery was more microscope-centered.
